Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448062, here are decompositions:

5 + 31448057 = 31448062
29 + 31448033 = 31448062
101 + 31447961 = 31448062
131 + 31447931 = 31448062
251 + 31447811 = 31448062
263 + 31447799 = 31448062
293 + 31447769 = 31448062
311 + 31447751 = 31448062

Showing the first eight; more decompositions exist.
